Title:
METHOD BY WHICH UE PERFORMS INITIAL ACCESS TO BASE STATION IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/172631
Kind Code:
A1
Abstract:
Various embodiments disclose a method by which a user equipment (UE) performs initial access to a base station by using a large intelligent surface (LIS) in a wireless communication system, and a device therefor. The method comprises the steps of: receiving, through the LIS, a UE search signal transmitted by the base station; transmitting an initial access signal to the base station through the LIS on the basis of resource allocation information included in the UE search signal; transmitting a first LIS control signal for controlling a reflection pattern of the LIS for an uplink signal; and receiving, through the LIS, an initial access response signal transmitted by the base station.
